Study of the outer water network of chavria dam in chalkidiki perfecture and water treatment installation

Chavrias River is one of the major rivers in the area of Chalkidiki, with a total inflow capacity up to 47.2 x 106 m³ per year. After construction, the dam will irrigate over 3,400 hectares and will supply with drinking water 42 cities and villages, with approximately 10.50 hm³/yr. The feasibility, the preliminary, the detailed design and the tender documents will be included. The water supply transmission and distribution networks are consisted of: (a) 125,970 m long HDPE pipework , (b)146,648 m long steel pipework, (c) six (6) water reservoirs of 8,250 m³ each, (d) eleven (11) pumping stations and (e) water treatment plant installations with capacity of 1.88 m³/sec (= 162,432.00 m³/d). The feasibility study of a 500 m hydraulic tunnel and the 400 m water transfer pipe from the dam and the water treatment plant was also included.
